dear sir,

I am having 3-layer blown film plant. Die diameter is 400mm and my maximum width of film is 1750mm. I want to produce shrink film which can have shrinkage % in MD 80% and TD 30 %,

I have run film with all layers 85% LDPE ( 0.3 MFI) + LLDPE 15% ( 1.0 mfi ) I am getting shrinkage in MD 80% but in TD i am getting 24 %,

Please can you suggest me any process parameter to get shrinkage 30% in TD( transverse direction ),

Thanking you in advance with best regards,

Mitul chavda.
